Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed. May 17, 1905. Serial No. 260,8l.

T0 (ti/7 whom it may concern:

Be it known that I, JOHN WARBURTON KING, a citizen of the United States,and a resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements inLatera'lly-Movable Dumping-Vehicles, of which the following is aspecification.

My invention relates to improvements in laterally-movabledumping-vehicles, particularly to laterallymovable dumping-ears.

It has for its object the provision of means for maintaining the centerof gravity of the box in its entire turning movement over the point oisupport, whereby a box of the maximum weight maybe dumped and returnedby the minimum amount of power.

It has for a further object to provide a de vice of the character setforth embodying advantages in point of perfect operation, strength,durability, and simplicity and inexpensiveness of construction.

In the drawings, Figure 1 is an end view of a car. Fig. 2 is a framentary vertical sectional view of the uncIerlrame and box of a car,showing my improvement applied; and Fig. 3, a fragmentary sectional viewtaken on the line 3 3 of Fig. 1. i

In all the figures of the drawings illustrating my invention likereference characters designate corresponding parts.

Referring to the drawings, 1 designates the truck at one end of the car,2 the underirame, and 3 the box, having side doors 3 and 3 all of whichparts, being of well-known construction and forming no part of myimprovements, need not be described in detail.

A plurality of transversely-extending raceways 41, of which only one isshown, are sus pended from the box of the car onlongitudinally-extending Z-bars 5 and 6, and each raceway consists oftwo parallel plates 7 and 8, the plate 7 having an integraldownwardlyextending rounded projection 9 and the plate 8 having anintegral downwardly-extending rounded projection 10 like that of theother plate and a laterally-extending integral projection 11, contactingwith the plate 7, so as to space the plates apart and form a continuouspassage 12, open at the bottom and ends and having balls 13 therein,said plates being secured together by bolts 13, having nuts 13 thereon.

A plurality of transverselyextending tracks 14, of which only one isshown, are supported on the underi'rame 2 of the car, and each consistsof a central arched portion 15, projecting through the opening in thebottom and ends of the raceway into engagement with the balls 13 to forma track therefor and having on each side at one end integralinwardly-inclined bearings 16 and 17 and on each side at the other endintegral inwardlyinclined bearings 18 and 19, the rounded projections10, adapted to engage and rock on said bearings in the dumping andreturn movement of the box.

Other antifrietion devices may be substi tuted for the balls 13.

By means of the supports on the underi'rame on which thedownwardly-extending projections on the box rock while said box iscompleting its lateral movement it is given a simultaneous lateral androtary movement.

I have not herein shown any means for moving the box laterally to dumpor return it, as this does not form a part of my present invention; butany of the well-known means may be employed, preferablypneumaticallyoperated means.

The operation is as follows: Suitable power is exerted to cause the boxto move laterally along the track 1 1say to the right-until the roundedprojections 9 and 10 strike the bearings 18 and 19, respectively, androck thereon up the inclined surfaces, elevating and turning the body tothe side in the position shown in dotted lines, Figs. 1 and 2, andallowing the contents to run out, after which power is exerted to causethe box to rock down the inclined surfaces of the bearings 18 and 19,turning and lowering the box and finally moving it along the track 14 toits normal position, as shown in full lines, Figs. 1 and 2.

I do not wish to be understood as limiting myself to the precise detailsand arrangements of parts shown and described, but reserve the right toall modifications within the scope of my invention.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a vehicle, the combination with theunderi'rame having a track and lateral bearings, of thelaterally-movable box provided with antifriction means engaging saidtrack and downwardly extending projections ada ted to engage and rock onsaid bearings W e the box is completing its lateral move ment andthereby impart simultaneous rotary movement thereto, substantially as described.

2. In a vehicle, the combination with the underframe having a track andlateral inclined bearings, of the laterally-movable box provided withantifriction means engaging said track and downwardly-extendingprojections adapted to engage and rock on said bearings While the box iscompleting its lateral movement and thereby impart simultaneous rotarymovement thereto, substantially as described.

3. In a vehicle, the combination with the underframe having a track andlateral bearings, of the laterally-movable box provided withdownwardly-extending rounded projections adapted to engage and rock onsaid bearings While the box is completing its lateral movement therebyimparting simultaneous rotary movement thereto, substantially asdescribed.

4. In a vehicle, the combination with the underframe having a track andinclined lateral bearings, of the laterally-movable box provided withantifriction means engaging said track and downwardly-extending roundedprojections adapted to engage and rock on said bearings while the box iscompleting its lateral movement therebyimparting simultaneous rotarymovement thereto, substantially as described.

5. In a vehicle, the combination with the underframe having a track andlateral bearings, of the laterally-movable box provided withantifriction means engaging said track and downwardly-extending roundedprojections adapted to engage and rock on said bearings while the box iscompleting its lateral movement thereby imparting simultaneous rotarymovement thereto, substantially as described.

6. In a vehicle, the combination with the underframe having a track andlateral bearings, of the laterally-movable box provided with a raceway,antifriction devices therein engaging said track and downwardly-extending projections adapted to engage and rock on said bearings while thebox is completing its lateral movement thereby imparting simultaneousrotary movement thereto, substantially as described.

7. In a vehicle, the combination with the underframe having a track andlateral inclined bearings, of the laterally-movable box provided with araceway, antifriction devices therein engaging said track anddownwardlyextending rounded projections adapted to engage and rock onsaid bearings while the box is completing its lateral movement, therebyimparting simultaneous rotary movement thereto, substantially asdescribed.

8. In a vehicle, the combination with the laterally-movable box providedwith downwardly-extending projections and a raceway having a continuouspassage open at the bottom, antifriction devices therein, of theunderframe having a track projecting through the opening in the racewayinto engagement with said antifriction devices and lateral bearingsengaged by said projections while the box is completing its lateralmovement thereby imparting simultaneous rotary movement to said box,substantially as described.
